The Lowdown
Alright, Rusty here, checking in on the stretch ahead for our little slice of the world.
Right off the bat, we’ve got a solid run of long-period groundswell heading our way, and it’s going to be sticking around for a good while. The water is sitting at a balmy 80°, which is pretty average for this time of year – nothing to write home about, just your usual tropical warmth.
The standout session that has me buzzing is Saturday, September 20th. That Sunday afternoon slot is looking proper. We’ve got a 7ft swell hammering in from the SW, pushing serious energy, and with a 16-second period on it. Winds are light and cross-off from the SSE, so Lakey Pipe is going to be clean and lined up. This is the one to circle. The morning of the 21st is also a top pick, with 7ft SW swell at 15 seconds and light offshore winds – it’s going to be a ripper, but expect company because this spot gets crowded often.
The early part of the run, starting Tuesday the 15th through the 19th, is all about consistent, clean, intermediate-friendly surf. Swells hang around the 4ft to 7ft range, with light to gentle cross-off breezes. The energy is moderate to strong, and those 14-15 second periods are giving the waves a real push. It’s not giant, but it’s quality. The morning of Wednesday the 16th with 6ft and light winds is a sneaky good one.
After that first big weekend, we’ve got a pulse that carries through the next week. The 23rd of September is another heavy hitter: a 7ft SSW groundswell on Wednesday afternoon, with massive energy. Winds are cross-off, so it’ll be clean. Just keep in mind that with a 16-second period, the sets might be a little fat on the take-off, but the power is there. The 24th and 25th offer slightly smaller but still excellent conditions for experienced surfers.
Now, a word of warning for Sunday, September 27th. The swell is forecast to hit 10ft from the SSW with an 18-second period – that’s a proper mountain of water. For this break, that’s too big for anyone but experts, and even then, it’s pushing the limit. If you’re not solid, give it a miss.
The very end of the month, the 29th and 30th, sees the size easing back to a more manageable 5ft to 6ft, still with clean conditions. It’s not the big show, but it’s a fun, mellow way to finish the run.
Overall, we’re spoiled for choice. If I have to pick one absolute standout, it’s Sunday, September 20th afternoon – that SW groundswell at 7ft with light winds is the whole package. Don’t sleep on the morning of the 23rd either, even though it’s a touch bigger. Grab your board and get after it.
Rusty.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
